Paul III was the patron of Michelangelo, whom he convinced to paint the the Last Judgement in the Sistine Chapel. The great artist was over seventy when he had completed this monumental masterpiece and the pope ordered him to direct construction of the new St. Peter's Basilica in 1546. It is well known that Michelangelo accepted the assignment and refused any form of payment, because he wanted to work to "render glory to God, honor to St. Peter and for the salvation of his soul." Upon the death of the pope, Michelangelo wrote, "Pope Paul III only showed me kindness." This majestic, impressive monument was sculpted by Guglielmo Della Porta and it shows Michelangelo's influence, especially in the figure of the Pope. Ravaged by age and pain, he is shown blessing the figures of Justice and Prudence. The first is actually a portrait of the pope's sister Julia, famous for her beauty. The second is his mother, Giovannella Gaetani, a strict, dignified old woman who resembled the Cumaean Sybil Michelangelo painted in the Sistine Chapel Originally, this monument which was in the Gregorian Chapel was decorated with two other statues, Peace and Abundance. In 1628 it was moved next to the Chapel of the Cathedra by order of Pope Urban VIII who had commissioned Bernini to build his tomb on the opposite side.
